conditions could cause internal bleeding.
• For specific information on your blood pressure, contact your physician. Never make any
judgment on your own regarding measurement results.
• Do not use this product along with implantable or wearable medical electrical equipment
such as pacemakers, defibrillators, or electrocardiographic monitors. This product is also not
intended to be used with HF surgical equipment.
• Do not use this product in an explosive environment such as near flammable anesthetics or
inside an oxygen chamber.
• The system may fail to yield the specified measurement accuracy if operated or stored in
temperature or humidity conditions outside the limits stated in the specifications section of
this manual.
• Do not use cuffs or accessories other than those specified by the manufacturer. Otherwise,
correct measurement readings cannot be obtained.
• Use of this product in areas near mobile phones, microwave ovens or other devices with a
strong electromagnetic field may cause malfunctions.
• Do not press the output plug of the AC adaptor during measurement.
• Do not disassemble or modify the product.

• Blood pressure is the force exerted by the heart in pumping the blood through the arteries and the
resistance by the veins to this flow.
• Blood pressure varies all the time, influenced by mental and physical factors, and is never
constant.
In general, blood pressure is highest during normal working hours and gradually decreases during
the afternoon and evening hours. It is low during sleep and increases at a relatively fast rate after
arising from bed.
The following are the main causes for changes in blood pressure:
– Body movement
– Conversation
– Mental tension
– Nervousness
– Emotions
– Eating
– Drinking alcohol
– Smoking
– Room temperature
– Recent urination or bowel movement
– Changes in the surroundings such as movement or noise, etc.

Install batteries and activate the clock before use. Measurement can be made without the clock being
activated. However, activating the clock allows you to save the measurement date and time with
readings for better review. The clock is deactivated as the batteries are removed. The product can be
also operated with the AC adaptor.
Installing batteries.
¥
Open the battery compartment cover, by
pressing the projection on the bottom of the
main unit.
Install four "AA" type batteries into the compartment.
• Make sure that the polarities correspond to the (+) and (–) marks inside
the battery compartment.
• Batteries can be easily installed or removed by pushing their (–) ends
against the spring.
Close the battery compartment cover completely until you
hear a click.
Battery symbol [
] will flash when battery power is low. Measurement can not be made while the
symbol is displayed. Replace the batteries. All four batteries need to be replaced with new ones; do
not mix new and old batteries or different batteries.
• The symbol might appear only during measurement although you can review readings in memory.
This is because more battery power is required for conducting a measurement, e.g. inflating the
cuff, than displaying the readings in memory. Replace the batteries.
• The enclosed batteries are for monitoring, and their life may be shorter than that of commercial
batteries.
• Do not inflate the cuff when it is not wrapped around your arm.
• Do not apply the cuff over a wounded arm, an arm of which side is under an intravascular
access or therapy or an arterio-venous shunt, or an arm on the side of a mastectomy.
Otherwise injury may result.
• Make sure that inflation of the cuff is not causing prolonged impairment of blood circulation.
Also, be cautious about temporary loss of the functions of any other medical equipment if any
monitoring equipment is used on the same limb with the blood pressure measuring cuff.
• To avoid injury due to interfered blood flow from cuff inflation,
– Make sure that the air hose is not twisted before measurement. Otherwise, cuff inflation
may not be conducted properly and prolonged, and
– Do not make measurements repeatedly.
• To avoid any possibility of accidental strangulation, keep this product away from children and
do not drape the air hose around your neck.
• Because the product includes precision parts, avoid extreme temperature variations,
humidity, shock, dust, and direct sunlight. Do not drop or strike the product. Make sure not to
expose it to moisture. This product is not water resistant.
• Do not press the display and operation buttons or place the main unit with the display face
down.
• Do not take out batteries or unplug the AC adaptor when the unit is turned on. Be sure to
switch off the unit before removing batteries or the AC adaptor.
• Let a qualified physician interpret your blood pressure readings.
Depending on your age, weight and general condition, blood pressure can be slightly different.
Consult with your doctor on determining what blood pressure is normal for you.
• Blood pressure measured at home tends to be lower than when measured in a hospital, clinic
or doctor's office.
This is because you are tense at the hospital and relaxed at home. It is important to know your stable
normal blood pressure at home.
• Before taking blood pressure, rest for approximately five minutes and take your blood pressure
while relaxed in a quiet environment.
• Measure blood pressure using the correct posture and do not move or speak during measurement.
• Avoid exercise, eating, drinking alcohol, smoking and other activities that affect your blood
pressure right before a measurement.
• Take your blood pressure at the same time every day.
• The ambient temperature should be approximately 20˚C when you take your blood pressure.
• Readings may vary slightly, depending on posture, whether sitting or lying.
Adjust the date/time and activate the clock.

You can also adjust the date and time automatically by connecting the unit with NISSEI
HealStyle App via Bluetooth. Refer to page 4 for the Bluetooth connection.

standby.
OPERATION WITH AC ADAPTOR
Connect the AC Adapter to the AC connector located at
the side of the main unit.
• Use the designated AC adaptor only.
• It is suggested to take out the batteries when using the adapter. However, the clock is deactivated
as the AC adaptor is unplugged so you may wish to insert the batteries to keep the clock activated.
In such a case, please make a few measurements without plugging in the adaptor to avoid a battery
leak.
• Do not connect the AC adaptor to any power socket where accessibility is not satisfactory.
Protection: This device is double insulated and protected against short circuits and overload by a
primary thermal fuse.
